新聞:AB模塊1769-CRR1現(xiàn)貨三菱plc中的LRC校驗(yàn)碼程序的編寫，在PLC與設(shè)備進(jìn)行通訊時采用MODBUS協(xié)議時，一般會有兩種數(shù)據(jù)模式，1是RTU模式，2是ASCII碼模式。RTU的數(shù)據(jù)傳輸采用CRC校驗(yàn)，而ASCII碼則采用LRC校驗(yàn)值。LRC值校驗(yàn)涵蓋從從機(jī)地址到數(shù)據(jù)的信息部分，校驗(yàn)和等于所有參與校驗(yàn)數(shù)據(jù)的字符和的補(bǔ)碼。我們先說下具體的校驗(yàn)碼怎么計算，然后說三菱plc的LRC校驗(yàn)碼程序的編寫。例子1采用ASCII碼模式控制變頻器指令：010321000001，這條指令中01一般是站號，03是讀取命令，2100是參數(shù)地址(運(yùn)行頻率)，0001代表數(shù)據(jù)的個數(shù)。
